TALKING-MACHINE;

application filed September 6, 196%.

To all whom it may coat-em Be it known that we, Ernnroon R. JOHN- son and VVILBURN N. DENNISON, both citiing the movement of Zens of the United States, and residents of the city of Philadelphia, State of Pennsylvania, and Camden", State of New Jersey,

' respectively, have invented certain new and llafiflll' lmprovements in Talking-Machines, of which the following is a fulL-clear, and

"complete disclosure.

The mainobjects of this invention are to provide in a talking machine improved means tor supporting a sound box either in q perative relation with a record or in an inverted'inoperative position above the rec-- 0rd; to provide improved means for limitthe sound box downwardly from its operative position; to providein combination with other elements adjustable means for. counterbalancing the sound box; and to provide other improvements as will appear hereinafter.

In the accompanying drawings, Figure 1 is a fragmentary side elevation of a talking machine constructed in accordance with this invention, the partsthereof being shown-as in operation; Fig. 2', a fragmentary side elevation; partly in vertical section, of a por-' tion of the same, the parts thereof being shown in inoperative position; Fl 3 afragmentary top plan view of a portion of the same; and Fig. t a fragmentary side elevation showing a counterbalance for'the sound box. teferring to the drawings, one embodimentof this invention comprises a cabinet mounted to rotate abouta vertical axis to support a horizontal disk sound record 3, the turntable being rotated by a suitable motor (not shown) arrzmged within the cabinet l.

llor supporting sound reproducing and above and upon which a turntable 2 is sound amplifying means,' a longitudinally curved supporting bracket 4 is attached at one end to the rear wall of the cabinet and extends outwardly and then upwardly there-- from and carries at its upper end and projecting niwardly therefrom a. horizontal col- Specification of Letters Patent.

lar'5. Arranged below and coaxiztlly with the collar 5 is a spring pressed pin or pivot 6 which pro ects upwardly from and is carried by the bracket 4. l l ithin the collar 5 is fixed a relatively short vertical tube 7 which projects slightly above and below the collar 5. The lower end of the tube 7 telescopes ovcr a-flange on the upper end of a hollow vertical hub 8 the lower end of which is closed and provided with a suitable recess in which engages the upper end of the pivot 6.

For supportinga sound box and for conveying sounds from the sound box to the interior of the arm 9. The disk 10 has an extension 11" which pxloject's forwardly therefrom .in a plane therewith and then turns laterally outwardly at right angles thereto and then rearwardly in a direction parallel to the disk 10, to form a guide 12,

the function of which will be described hereinafter. The disk 10 also has a flat eX- tension 13 projecting rearwardly therefrom in a plane therewith and in contact laterally with the tone arm 9 and attached thereto for considerable fraction of the length of the arm. 1

For c nnecting a sound box to the "tone arm v9, a substantially fiat elongated sound box frame or support 14: is pivotally connected'to the arm 9 by means of a horizontal screw 15 at the inner end of the flat extension 13 on the arm, to oscillate in a vertical plane-about the axis of the screw and'in.

sliding contact withthe fiat surfaces of the disk 10 and its extensions 11 and 13. The frame 14 is widened .nearits outerlend to form a disk shaped portion 14 of substantially the same diameter as the disk 10 fixed on the tone arm, the di shaped portion 14 being arranged to be approximately coaxial extensions, when the sound with the disk 10 when the sound box is in operation.

Fixed upon the disk shaped portion l-l' of the frame 14; and substantially coaxial therewith is a sound box 16 ot' a well known construction and provided with an outlet 17 arranged to be substantially in line with the opening 11 in the tone arm when the sound box is in position for recording or reproducing sound, and the disk shaped portion 14; is provided with a corresponding opening to permit the sound box 16 to communicate with the tone arm 9.

To insure a'practically sound tight joint between the sound box 16 and the tone arm 9 when the sound box is in operation, the

outer "free end of the frame ll is arranged and proportioned to engage snugly but slidably in the guide 12 to maintain the frame in sliding contact with the disk 10' and its box is -in an operative position.

To limit the rotary movement of the sound box about its pivot 15 the sound box in an inverted inoperative position above a record 3 on the record sup port 2', a horizontal. pin or stop 18 is fixed to the tone arm 9 and projects laterally therefrom into the path of the frame 14.

To limit the downward movement of the sound box 16 from its operative position with respect to the tone arm 9, to prevent the sound box from falling into contact with the cabinet 1, should the sound box be moved laterally out of contact with the record, the frame 14 is provided with a pin or stop 21 arranged to engage the upper edge of the extension 11' on the tone arm 9 at a point in the movement of the sound box when the sound box is slightly below its lowermost operative position with respect to the tone arm.

4 For amj'ilifying the sounds delivered from the sound box through the tone arm 9, hub 8, and short tube 7, any suitable sound amplifier or horn 20 may be arranged to connnunicate with the short tube 7, the horn being preferably arranged with its smaller end in telescopic relation with the upper end of the short tube 7 and resting upon the collar 5 so that the horn may be swung about the vertical axis of theshort tube 7 to deliver the sound in any desired horizontal direction.

To adjust the downward pressure of the sound box against a sound record, the sound box may be provided, as shown in Fig. 4., with an adjustable coimterbalance, preferably in the form of a counterweight 23 adjustable longitudinally of a counterbalance arm 22 formed on the inner end of the frame 14 and projecting rearwardly therefrom when the sound box is in operative position. The counterweight 23 is held in and to support any desired position of adjustment longitudinally of its arm 22 by means of a set screw 24. By means of this adjustable counterweight the downward pressure of the stylus against the record may be adj listed so as to avoid unnecessary Wear upon the record, and obviate I or minimize scratching or grating, thus prolonging the life of the record and improving the quality of the reproduction.

It is thought that the construction and operation of this device will be fully understood from the foregoing description. it is to be noted that in the operation of the device, the tone arm 9 swings in a plane substantially parallel to and above the record.

3 and record support 2 about a vertical axis, and the sound box 16 swings laterally i'n unison with the tone arm 9 and also swings vertically with respect to the tone arm about a horizontal axis fixed with respect to the tone arm and extending transversely with respect to the longitudinal axis of the tone arm.

t is to be understood that this invention is not limited in its application to the specific construction hereinbefore described but might be applied in various forms without departing from the spirit of the invention or the scope of the appended claims.

Having thus fully described this inven tion, we claim and desire to protect by Letters Patent of the United States:
